In this second tutorial we will explain how a surd expression under a second square root is dealt with as well as explain two other typical surd problem solving techniques, namely, surd term factoring and coefficient equalization of surd and non-surd terms in a surd equation. We will explain through the process of solving chosen SSC CGL level problems...
Because of the easy systematic steps most likely we would be able to solve a problem quickly and wholly in mind by Componendo dividendo. In this session we have shown how problems not directly conforming to the Componendo dividendo can still be solved quickly using the concepts of Componendo dividendo...
We have seen Componendo dividendo to simplify competitive math problems in many topics so much so that the problems could usually be solved in mind. In this session we will highlight the power and elegance of the three-step simple process in the area of Algebra with three examples...
Surds are a special group of irrational numbers that can be represented easily in compact form as $\sqrt{2}$, $\sqrt{3}$ etc. In addition, a number of quick math methods in simplifying surd problems make this topic a favored one for testing problem solving abilities in schools and competitive tests...
We have seen Componendo dividendo to simplify competitive math problems in topics as diverse as—number system, ratio and proportion, surds, trigonometry or algebra. Oftentimes it plays a key role in solving the problem quickly...
A simple or compound event (consisting of more than one event) goes on happening systematically at regular intervals till a point just before the end. With each occurrence of the event problem parameters change. The end is reached before the full impact of the event along with the change can happen. This is the boundary to be found out before solving the problem...
In 42 days 40 men complete a work. As it happened, instead of all of them working together to finish the job, they started working together, but at the end of every 10th day 5 men left. In how many days would then the work be completed? Rich time and work concept of Mandays technique along with natural number concepts deliver speedy solution...
C and A can do a piece of work in 20 days, B and C in 24 days, and A and B in 30 days. B and C leave after three of them work together for 10 days. In how many more days would A complete the work? Using rich concept of Work rate technique and solving the problem as far as possible in mind, without writing anything on paper, results in within a minute solution...
